Bricks are the most important component in the building industry, for which several types are available across the world depending upon the availability of the basic manufacturing materials. In India, burnt clay bricks are the most sought-after type for which enormous quantities of top fertile soil are being harnessed. Efforts are being made to reduce the self-weight of these bricks while retaining the strength requirements. The present study is an effort to utilize the locally available agro-waste materials along with the native black cotton soil. Trial mixes were investigated for their relative effectiveness in order to get the optimum mix combination. In the first trial, the black cotton soil mixed with 10% RH and 10% RHA, the dry density is obtained as 1.32 g/cc. In the second trial, in order to reduce the dry density further, the RH and RHA contents were increased to 20% at which the dry density is obtained as 0.90 g/cc. Despite the encouraging reduction in self-weight, the burnt bricks at 800 °C were observed to be subjected to self-cracking after exposing them to environment within 24 h. In order to overcome the cracking problem, the straw fibers were tried along with the RH and RHA. Even then, the problem of self-cracking could not be overcome. In further trials, locally available red soil is mixed with black cotton soil by 10–20%, and also the burning temperature is increased up to 1000 °C by which the cracking problem could be overcome while maintaining the lower density. The strength of the bricks is obtained as about 73.49 kg/cm2 satisfying the requirement for the II-class bricks as per IS:1077 (1992).
